Expression, purification, crystallization and crystallographic study ofLutzomyia longipalpisLJL143 [PDF]

Acta Crystallographica Section F Structural Biology Communications, 2015
Leishmaniasis is a neglected vector-borne disease with a global prevalence of over 12 million cases and 59 000 annual deaths. Transmission of the parasite requires salivary proteins, including LJL143 from the New World sandflyLutzomyia longipalpis. LJL143 is a known marker of sandfly exposure in zoonotic hosts.
